Culture-independent molecular techniques brought new perspectives for research regarding soil microorganisms, which is relevant to microbiologists and industry. Therefore, new research is necessary to broaden our knowledge about ecology and physiology of mycobacteria in extreme environments. The aim of this study was to verify the presence of mycobacteria in Antarctica soil samples and to standardize molecular and culture-dependent techniques to their isolation. Soil DNA was extracted and submitted to denaturing gradient gel electrophoresis (DGGE), rrs mycobacterial gene amplification and partial sequencing. Thereby, 10 colonies morphologically similar to mycobacteria were isolated from 10 different samples, resulting in 15 DNA sequences where Mycobacterium neglectum and Mycobacterium kumamotonense were identified, suggesting that Mycobacterium terrae complex representatives are ubiquitous in the region. This study proposes a simple method for mycobacteria cultivation from soil samples and shows that ornithogenic soils can be the source of organic matter and low pH, modulating the mycobacterial Antarctica diversity. Further research aiming to explore mycobacterial diversity in soil are needed to increase knowledge and better explore their evolution, their relation with animal and human species and their potential biotechnological use.","subitem_description_type":"Abstract"}]},"item_10001_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"10.1016/j.polar.2022.100890"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1016/j.polar.2022.100890","subitem_relation_type_select":"DOI"}}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"18739652","subitem_source_identifier_type":"ISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"de Barros, Caroline Reis","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Baethgen, Ludmila Fiorenzano","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Mastrobuono, Gabriela","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Peixoto, Raquel Silva","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Miranda, Karla Rodrigues","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"da Silva Carvalho, Ana Carolina","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"da Silva Dias, Rubens Clayton","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Rosado, Alexandre Soares","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Duarte, Rafael Silva","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Mycobacteria","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Soil samples","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Antarctica","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Mycobacterial diversity","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Mycobacterial diversity in soil samples from King George Island, Antarctica","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Mycobacterial diversity in soil samples from King George Island, Antarctica"},{"subitem_title":"Mycobacterial diversity in soil samples from King George Island, Antarctica","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"26","path":["2106"],"pubdate":{"attribute_name":"公開日","attribute_value":"2022-12-01"},"publish_date":"2022-12-01","publish_status":"0","recid":"16994","relation_version_is_last":true,"title":["Mycobacterial diversity in soil samples from King George Island, Antarctica"],"weko_creator_id":"26","weko_shared_id":-1},"updated":"2023-07-25T12:44:02.245508+00:00"}
